2log(m)y-log(m)x-log(m)z

2log(m)y-log(m)x-log(m)z log(3)4*log(4)8*log(8)M =log(2)16 M是多少呃.... 求等式log(2)3*log(3)4*log（4)5*log(5)6*log(6)7*log(7)m=log(3)9时m的值? log m=log 底数为2 对数为5024 log(a)M+log(a)N=? 若log m 3 若log(2)4·log(4)8·log(8)m=log(4)16,求m的值 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 log log log 可以说log a x +log a y=log a log【2】(log【8】m) =log【8】（log【2】m）,求（log【2】m）的平方 【】内为底 点(m,n)在直线x+y=1位于第一象限内的图像上运动,则log(2)m+log(2)n的最大值 若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4（x）)]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z= 已知log（14）7=a log(14)5=b 用ab表示log(35)70=log(3)4*log(4)8*log(8)m=log(4)2 求m 证明对数运算法则（1）log(a)(MN)=log(a)(M)+log(a)(N); 　　（2）log(a)(M/N)=log(a)(M)-log(a)(N);（1）log(a)(MN)=log(a)(M)+log(a)(N); 　　（2）log(a)(M/N)=log(a)(M)-log(a)(N); 　　（3）log(a)(M^n)=nlog(a)(M) （n∈R） 解不等式log(m)(10)≥2,
